Make numa_available respect EPERM
Make numa_available respect EPERM
In the Docker environment, usage of `get_mempolicy` is restricted by seccomp security profiles:
https://docs.docker.com/engine/security/seccomp/ (unless `CAP_SYS_NICE` is set).
But `numa_available` used to ignore EPERM and return 'true', i.e., available. This led to further code attempting other API calls, which resulted in "operation not permitted" errors printed to stderr.
